vIMPROVEMENT IN STOP MECHANISMS FOR SPINNING AND DOUBLING MACHINES.

Specification forming part of Letters Patent No. 1.117,65?, dated February 17, 1874; application filed To all whom it may concern:

Be it known that I, GEORGE KRAINK, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Spinning and Doubling Machine, of which the following is a specification:

The rst part of my invention consists of the bolster projecting below the bolster-rail, and having the loose pulley of the spindle on it, so that the spindle will be freed from the friction of the pulley when the belt is running on it, and thus will always stop when the belt is thrown off, whereas it frequently continues to run by the friction of the pulley on it when the latter runs directly on the spindle, which is the arrangement employed at the present time. The second part consists of a swing bar or tongue combined with the faller-wires of the stop-motion, a reciprocating bar moved forward and backward in front of it, and the tripping-rod of the shipper-bar, so that when a thread breaks and one of the taller-wires falls it will swing the said bar or tongue forward into the path of a projection on the reciprocating bar, and :it will thus be moved powerfully by the latter, so as to release the trip-rod to stop the machine. rlhe third part of the invention consists of a piece of cloth, leather, or other equivalentsubstance, and a slide with wedgelike prongs, combined with thc bobbin on which the thread winds from the spindle, the friction-roller which turns the bobbin, and lthe falling rod by which the spindle-belts are thrown oft' when a thread breaks, so that when the rod falls the cloth and the wedges will be moved forward between the bobbin and the friction-roller, the cloth being to stop the bobbin, so that it will not continue to draw the thread from the spindles after they are stopped, (the friction-roller being driven independently ot' the spindles, and, not being stopped when they stop,) and the wedges being to go under the journals or pivots of the bobbin to lift it, so that it will not press the i cloth or leather on the` friction-roller during the stoppage, and thus protect it as much as possible from wear by the roller. Y Figure l is a front elevation of my im- December 13, 1873.

proved machine. Fig. 2 is a sectional elevation taken on the line x of Fig. l, and Fig. 3 is a detail of the spindle-bolster and loose pulley.

Similar letters of reference indicate corresponding parts.

I extend the spindle-bolster A'suieiently' below the rail G, and mount the loose pulleyl D on it, and secure it by a llange or collar, E, so that the spindle will be entirely freed from the friction of the loose pulley when the belt is running on the latter, thus insuring the stopping of the spindle when the belt is thrown oft', which is not certain to be done when the pulley runs on the spindle. In order to lubricate the loose pulley in this arrangement, I arrange the upper end of the bolster a little below the holder F, so that some of the oil poured in to lubricate the spindle will ow down on the outside of the bolster to the pulley. J represents the swinging bar or tongue, which is thrown out by the fallerwires K into the path of the double-inclined projection L on the reciprocating bar M, so as to be struck by it and swing against the nipper N, which holds up the belt-shipper O, and cause it to push the said tripper, so as to throw it out from under the stud P of the belt-shifter, which rests on it, and let the latter fall to throw the spindle-belto the fast pulley Q, onto the loose one D by means ot' the lever S and rod T. Uis the slide to which the leather, paper, cloth7 or other strip Vis connected, so as to be moved forward by the shipper O when it falls. It is connected to the shipper by the bell-crank XV and connecting-rod Z, so that said strip V will be drawn by the friction-roller X between it and the bobbin Y, whereon the thread is wound from the spindles, and stop the winding whenever the spindle stops, and thus avoid winding the silk oft' the spindles, when they are not spin- Haring thus described n1 y invention, I ela-ini as new and desire to secure by Letters Patent- 1. The spindle-holster A, extended below the holster-rail and its holder F, and having the loose pulley arranged on it, substantially as Specified.

2. The combination of the Swinging tongue or bar J with the taller-Wires K, tripper N, the reciprocating bar M, havin g a double-inclined projection, L, and the shipper-bar O, substantially as specified.,

The combination of a paper, leather, cloth,

or other like piece, V, with the shipper-rod O, friction-roller X, and bobbin Y, to stop the latter when the shipper falls and stops the spindle, substantially as specified.

el. The combination of' the Wedge-shaped slides a with the leather or cloth strip V, the shipper O, and the hobbin and bobhin-turning roller X, substantially as specified.

GEORGE KRAINK.
